cockroach , snails and clams have already become aliveness batteries as experimental cyborgs . A new MIT fuel cell could offer that futurist approximation to human being by drawing its power from the fluid surrounding the human brain .
The fuel cell can already make enough power for low - powerbrain implant — gadget that could eventually help paralyzed patient move their pegleg and implements of war again . MIT researchers made the fuel cadre out of Si and platinum so that it can last for years with a low endangerment of provoking the physical structure ’s immune response .
This silicon wafer consists of glucose fuel cells of varying sizes; the largest is 64 by 64 mm.
" The glucose fuel cell , when combined with such extremist - low - power electronics , can enable mental capacity implants or other implant to be entirely ego - powered , " enjoin Rahul Sarpeshkar , an associate professor of electrical engineering and computer science at MIT .
MIT ’s fuel cell mimics the office of the human organic structure ’s enzymes by collapse down glucose sugar into DOE . The glucose in the brain ’s cerebrospinal fluid represents a continuous fuel supplying for the fuel cellphone — even if the fuel cadre currently generates just hundreds of microwatts ( one microwatt is equal to one one-millionth of a watt ) .
Scientists had already shown they could power a heart pacemaker with glucose fuel cells in the 1970s , but they kick in up on the idea because such fuel cells used biological enzymes that finally wear out . MIT ’s fuel cell head off that problem by bank on nonbiological materials . [ Cyborg Snail Turned into Living Battery ]
" It ’s a proof of concept that they can generate enough power to run across the requirements , " said Karim Oweiss , an associate professor of electrical engineering , data processor science and neuroscience at Michigan State University .
A next footprint for MIT involve showing how well the fuel cell work in living animate being , Oweiss enjoin . Other researchers have already shown how modest creature such ascyborg clamsand cyborg snail can refuel engraft fuel cubicle with their own bodies .
Sarpeshkar ’s MIT lab previously worked on implantable devices that bridge the opening between brain and simple machine — transcription and decoding nerve signaling , stimulating nerves , or communicating wirelessly with brainpower implants . But aesculapian implant capable of harvesting get-up-and-go from a person ’s own somatic fluids remain years away .
" It will be a few more year into the time to come before you see hoi polloi with spinal - cord injuries receive such implantable systems in the circumstance of standard aesculapian guardianship , but those are the sorts of devices you could envision powering from a glucose - based fuel cell , " enjoin Benjamin Rapoport , a former alumnus student in the Sarpeshkar science lab and the first generator on the novel MIT report .
The study is detailed in the June 12 online variation of thejournal PLoS One .
